Space frames are models that have a sparse distribution of elements, such as a car body.  Space frame models can generally have element counts in the hundreds of thousands, but their basic structure is rather simple.  Often the desired shape changes are general, such as making it smaller, shorter, wider, or altering the basic positions of components within the frame.  In many instances, these changes can be performed by placing a handle at each joint in the frame and moving those handles to the desired locations.  For these types of models, all that is necessary is to create a global domain and global handles.  Local handles are not required since local changes to the frame components are not necessary.  Since local handles and domains for large models can consume a great deal of resources, you should avoid creating them unless it is necessary.
